Estimated Glomerular Filtration Rate
A Vital Marker of Kidney Health in Diabetes
The eGFR test (Estimated Glomerular Filtration Rate) is a crucial kidney function test that estimates how efficiently your kidneys are filtering waste from your blood. For individuals living with diabetes, monitoring kidney function through the eGFR test is essential for the early detection and management of diabetic kidney disease.
What Is eGFR?
The eGFR test is calculated using your serum creatinine level, age and gender. It estimates how much blood your kidneys filter each minute. A normal eGFR reflects healthy kidney function, whereas a low eGFR may indicate chronic kidney disease (CKD) or kidney damage due to diabetes.
Why Is the eGFR Test Important for People with Diabetes?
Diabetes is the most common cause of chronic kidney disease. Over time, high blood sugar can damage the delicate blood vessels in the kidneys, reducing their filtering ability.
The eGFR kidney test helps to:
- Detect the early stages of kidney damage
- Track the progression of diabetic kidney disease
- Support clinical decisions on medications and referrals
eGFR Ranges and Their Meaning
| eGFR Value (mL/min/1.73m²) | Interpretation |
|---|---|
| 90 or above | Normal kidney function |
| 60 – 89 | Mild decrease (early kidney disease) |
| 30 – 59 | Moderate decrease (Stage 3 CKD) |
| 15 – 29 | Severe decrease (Stage 4 CKD) |
| Below 15 | Kidney failure (Stage 5 CKD) |
When Should You Take the eGFR Test?
- At least once a year for all individuals with diabetes
- Every 3 to 6 months if you have existing kidney disease or high blood pressure
- When experiencing symptoms like fatigue, swelling, or changes in urination
Knowing how often to take the eGFR test in diabetes helps ensure early intervention and better outcomes.
How to Protect Kidney Function
- Maintain good blood sugar and blood pressure control
- Reduce salt and excess protein in your diet
- Stay well-hydrated and physically active
- Avoid self-medicating with over-the-counter painkillers
